Make sure that nobody pays back wrong for wrong, but always strive to do what is good for each other and for everyone else. 1 Thessalonians 5: 15
One thing is certain... revenge or "payback" doesn't end the conflict... it only escalates the trouble. It makes things worse, not better.
Instead of searching for revenge, why not attempt to be the bigger man. Stand tall and refuse to stoop to childish behavior. The man with poise and restraint is the one in control. God can help you with that.
It can be difficult keeping a lid on your urge to "make them pay for what they did." First, confess your anger and off-load it quickly. The longer it cooks under the surface, the more likely you will be to act. Second, pray for the strength to forgive - this is where life and freedom live.
